Ephemeral transit on the spotless Sun

The Earth-facing side of the Sun has been spotless these past days. But on this image, a transit of the International Space Station (ISS) breaks this monotony. The ISS was 485km (300 miles) away and traveling 27,000 km per hour (17,000 mph) when I took this image. The total transit duration was 0.68 seconds, so needless to say that precision is key to record this type of image. The image is a composite of three frames, taken 0.27 seconds apart (the maximum speed allowed by my camera in the burst mode). Technical details: Telescope Orion 80ED (refractor) + powermate 2x, Camera: Canon T2i (550D), 1/4000th @1600 ISO. Image taken on July 17th 2014, at 11:55am
